Title: Drifting petroleum deposit development at late stage
Inventor: FEDIN A K
IPC: E21B43/16
Filed: 2003-05-29
Granted: 2004-02-20
Abstract: FIELD: petroleum extracting industry. SUBSTANCE: development method includes extraction from all supplying wells bored in deposit with lowering of their acceleration by no less than 70% of starting value and/or from all extracting wells with water denseness around extracted petroleum of no less than 80%. Periodical shutdown of wells operation is done in turn. Reaction of operating extracting wells is measured and controlled by quantity and/or speed and surrounding water denseness and/or gassing of extracted petroleum for determining wells for shutdown. Then reaction areas connected to shutdown of selected wells are determined. Then operating extracting wells are stimulated in determined areas by means of explosions done in turn in selected wells. Explosions are performed in wells near contour of selected areas. Explosions are pin-pointed with localization of their energy in the area of productive layer. For this in each of said wells water layer is opened with total area of perforation openings against this layer and productive layer equal to 30-75% of operating column cross-section area. In some wells explosions are performed against productive layer, in other wells explosions are performed against water layer. Some explosions are performed synchronously and/or in turn with one and/or different sides of each selected area and consequence of explosions is different relative to different layers. EFFECT: increased effectiveness of petroleum deposit development. 3 cl

Granted: 2005-05-10
Abstract: FIELD: chemical industry; biological industry. 
     SUBSTANCE: method and device can be used for testing biological, chemical and biochemical surface sensors which operation is based upon excitation of surface electromagnetic waves on surface of solid body. Change in phase of surface (or waveguide) wave is measured by means of interference between signal wave (waveguide or plasma) propagating along tested surface and volumetric reference wave propagating inside liquid directly above the surface at a small angle to the surface. Both interfering waves pass through liquid cell. One wave has shape of surface (plasma or waveguide) wave, the other one has shape of volumetric wave propagating directly above the surface. Change in volumetric parameters of liquid, for example, refractivity, influences both waves - signal surface and reference volumetric. The influence is mutually compensated in registered interference signal. Sensitivity to volumetric parameters of liquid is reduced while high sensitivity to properties of surface layer is kept. 
     EFFECT: improved precision.
